Question

Volume of Hemisphere
Volume of Sphere

Volume of Sphere

Answer 1

The volume formulas for a hemisphere and a sphere are as follows:

1. **Volume of a Sphere**:
The formula for the volume \( V \) of a sphere with radius \( r \) is:
\[
V = \frac{4}{3} \pi r^3
\]

2. **Volume of a Hemisphere**:
The formula for the volume \( V \) of a hemisphere (which is half of a sphere) with radius \( r \) is:
\[
V = \frac{2}{3} \pi r^3
\]

### Summary of Volumes:
- **Sphere**: \( \frac{4}{3} \pi r^3 \)
- **Hemisphere**: \( \frac{2}{3} \pi r^3 \)
